DPDK-based Improvement of Packet Forwarding

DPDK-based Improvement of Packet Forwarding

Reel-time processing of packets occupies a significant position in the field of computer network security. With theexplosive growth of the backbone link rate,which is consistent with Gilder's law, many bottlenecks of server performance leave the real-time data stream unprocessed.Thus, we propos...
